API(rte_bus_get_iommu_class) helps to automatically detect and select
appropriate iova mapping scheme for iommu capable device on that bus.
Algorithm for iova scheme selection for bus:
0. Iterate through bus_list.
1. Collect each bus iova mode value and update into 'mode' var.
2. Mode selection scheme is:
if mode == 0 then iova mode is _pa,
if mode == 1 then iova mode is _pa,
if mode == 2 then iova mode is _va,
if mode == 3 then iova mode ia _pa.
So mode !=2 will be default iova mode (_pa).

This commit adds a new flag that the component (or "backend")
can use to indicate readyness. The service function callback
will not be called until the component sets itself as ready.
The use-case behind adding this feature is eg: a service that
requires configuration before it can start. Any service that
emulates an ethdev will have rte_eth_dev_configure() called,
and only after that the service will know how many queues/etc
to allocate. Once that configuration is complete, the service
marks itself as ready using rte_service_component_runstate_set().
This feature request results from prototyping services, and
requiring a flag in each service to note "internal" readyness.
Instead that logic is now lifted to the service library.
The unit tests have been updated to test the component runstate.

When an application requests the use of a PCI device, it can currently
interchangeably use either the longform DomBDF format (0000:00:00.0) or
the shorter BDF format (00:00.0).
When a device is inserted via the hotplug API, it must first be scanned
and then will be identified by its name using `find_device`. The name of
the device must match the name given by the user to be found and then
probed.
A new function sets the expected name for a scanned PCI device. It was
previously generated from parsing the PCI address. This canonical name
is superseded when an rte_devargs exists describing the device. In such
case, the device takes the given name found within the rte_devargs.
As the rte_devargs is linked to the rte_pci_device during scanning, it
can be avoided during the probe. Additionally, this fixes the issue of
the rte_devargs lookup not being done within rte_pci_probe_one.

Some buses will operate either in whitelist or blacklist mode.
This mode is currently passed down by the rte_eal_devargs_add function
with the devtype argument.
When inserting devices using the hotplug API, the implicit assumption is
that this device is being whitelisted, meaning that it is explicitly
requested by the application to be used. This can conflict with the
initial bus configuration.
While the rte_eal_devargs_add API is being deprecated soon, it cannot
be modified at the moment to accommodate this situation.
As such, this new experimental API offers a bare interface for inserting
rte_devargs without directly manipulating the global rte_devargs list.
This new function expects a fully-formed rte_devargs, previously parsed
and allocated.
It does not check whether the new rte_devargs is compatible with current
bus configuration, but will replace any eventual existing one for the same
device, allowing the hotplug operation to proceed. i.e. a previously
blacklisted device can be redefined as being whitelisted.

Hotplug support introduces the possibility of removing devices from the
system. Allocated resources must be freed.
Extend the rte_devargs API to allow freeing allocated resources.
This API is experimental and bound to change. It is currently designed
as a symetrical to rte_eal_devargs_add(), but the latter will evolve
shortly anyway.
Its DEVTYPE parameter is currently only used to specify scan policies,
and those will evolve in the next release. This evolution should
rationalize the rte_devargs API.
As such, the proposed API here is not the most convenient, but is
taylored to follow the current design and integrate easily with its main
use within rte_eal_hotplug_* functions.
